I can answer your question if you have a picture or a writing, your welcome.
Pretty sure it's 1 but get 2nd opinion
B bubbles indicated a change
Answer:
.54 mol
Explanation:
Using the ΔH given for the balanced reaction, convert kilojoules to moles of CO2 using the stoichiometric ratio:
250 kJ×(6 moles CO22803 kJ)=0.5351 moles CO2
The answer should have two significant figures, so round to 0.54 moles CO2.
Notice that coefficients in stoichiometric equations (indicating numbers of moles) are exact, so they do not constrain the number of significant figures.
